Comment:

 Thank you for the report.

 I confirm this problem does not occur in 7.6.3, and does occur with 7.8.1
 and HEAD. I can not find anything about this in the 7.8.1 changelog. I did
 find a related change, but then for the GHC Api pretty printer.

     Print explicit braces and semicolons in do-notation

     By printing explicit braces we make it more likely that pretty-printed
     code will be acceptable if fed back into GHC.

     See http://www.haskell.org/pipermail/glasgow-haskell-
 users/2009-July/017554.html
